Custom Button Layouts please!

I believe I speak on a decent amount of the population of Halo Players when I say “we need custom button layouts in Halo 5.” I used to be decent at halo because the button layouts made sense, but no more. I shouldn’t have to remap my controller to play a game comfortably, nor should I try getting used to a terrible control scheme just to die over and over, and pushing me away from the Halo I use to enjoy.
